Culture of the mud crab, Scylla serrata, is beset by low and inconsistent survival of larvae in spite of the high fecundity of crab breeders. The nutrition of the embryo and pre-feeding zoea depends on what is stored in ...

This study was undertaken to determine the combined effects of temperature and salinity on the incubation time and hatching rate of Penaeus semisulcatus eggs in controlled laboratory conditions. Fertilized eggs, from a ...

An approach for evaluating multiple innovations of an aquaculture farm is proposed, based on a model of induced innovations, supplemented with a bio-economic table for the calculation of pro- duction function. Data gathered ...

Experiments were performed to investigate the influence of feeding frequency on growth, gonad weight and fecundity in an ornamental fish, Betta splendens. Five groups of 30-day-old juveniles (0.045±0.01 g; 14.43±2.2 mm) ...

The effects of fresh water and sea water on growth, estradiol-17β levels, ovarian and oocyte development of Oreochromis niloticus, O. aureus and Tilapia zilli were determined. Sea water affected growth positively (p<0.05) ...

The effects of salinity on the development and incubation of European squid (Loligo vulgaris, Lamarck, 1798) eggs were investigated from December 2001 to March 2002. The egg capsules were incubated in 37‰, 34‰, 31‰, 28‰, ...

The reproductive biology of the shi drum (Umbrina cirrosa) in culture was histologically exam- ined and sperm quality was monitored during an entire reproductive period. Already in April, the ovary contained oocytes in all ...

Quantification of the essential amino acid requirements of a species is required for formulating optimal diets for cultivated fish. In this study, crystalline L-phenylalanine was used to determine the quantitative phenylalanine ...
